PETER N. FORSYTH, OF PORTLAND, OREGON.

TRENCI-I-TOOL.

avasoa.

To all whom it may concern:

Be it known that I, PETER N. FoRsY'r'H, a citizen of the United Statesof America, residing at Portland, in the county of Multnomah and Stateof Oregon, have invented new and useful Improvements in Trench- Tools,of which the following is a specification.

The present invention has reference generally to improvements in toolsand more particularly relates to a trench tool.

It is the primary aim andobject of the present invention to provide adevice of the above character designed for use in digging trenches andin reality embodies in itself an ax, mattock, hoe and pick.

It is an equally important object of. the present invention to provide adevice of the above character the construction of which is novel and iscapable of being mounted on a handle and conveniently manipulated.

Among the other aims and objects of this invention may be recited theprovision of a device of the character described with a view tocompactness, and in which the number of parts are few, the constructionsimple, the cost of production low and the efficiency high.

Other improvements and novel details in the construction and arrangementof the various parts of the apparatus will be brought out more in detailin the description to follow, which for a clear understanding of theinvention should be considered in connection with the accompanyingdrawing forming a part hereof, and wherein is disclosed for the purposeof illustration, a convenient and satisfactoryembodiment of theinvention. It is to be noted in this connection that minor changes inthe construction and arrangement of parts may be made without departingfrom the principle of operation of the various parts. 1

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is a top plan View of the invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is an end elevation of the invention;

Fig. 4 is a transverse section taken on line 4-4, of Fig. 2;

Fig. 5 is a transverse section taken on line 5-5, of Fig. 2.

Similar characters of reference are em- Specification of Letters PatentvPatented Sept. 1918.

Application filed December 29, 1917. seria1No.209,444. Y

accompanying drawing, there is provided the improved tool embodying aneye 1 designed for detachably receiving a handle 2 while projecting inopposite directions from the eye are blades 3 and 4 both of which aretapered toward their outer ends as indicated by the numeral 5, while theextreme outer ends are beveled to provide cutting edges 6. The blades 3and 4 are also tapered toward their upper edges as at 7 while the upperedges are in turn sharpened as at 8. Subsequent to sharpening the toolit is desired that the blade 4 be heated and twisted as at 9 andarranged in a plane at right angles to the plane of one blade 3 thusdisposing the sharpened. edge 8 on one side of the tool as indicated.This blade 4 is capable of being used in the capacity of a mattock, hoeor pick while the blade 3 may be used in the capacity of an ax or as apick. It it apparent therefore that the structure provides in effect acombination tool while the cutting edges 6, 7 and 8 are so positionedthat they may be effectively brought into use when the operator desiresto make a peculiar stroke or cut. The device would also be useful inlumber camps; by farmers, miners, prospectors, etc. I

If desired, instead of twisting the blade 4 the same may be arranged inthe first instance in a plane at right angles to the plane of the blade3, this of course depending on the mode of manufacture.

It is believed that in view of the forego ing description, a furtherdetailed descrip- 7 from the scope thereof and it is intended that allmatter contained in the above description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitedsense. It is also to be understood that the language used in thefollowing claim is intended to cover all the generic and specificfeatures of the invention herein described and all statements of thescope of the lnventlon WhlCll as a matter of language might be said tofall therebetween.

Having thus described-the inventionlwhat is claimed as new and desiredto be secured by Letters Patent is i A device of the character describedincluding aneye, a handle detachably engageable With the eye, opposed.blades pr0jecting in opposite directions from the eye and integraltherewith and tapered from the eye toward their outer ends, the outeredges being sharpened, the blades being also tapered transversely.andsharpened at their re stricted marginal edges, and one of the bladesbeing twisted and arranged in a plane at right angles to the otherblade.

In testimony whereof I aflix my signature;
